i am thinking about getting the random tech cats, but i've heard that they aren't smog legal in california. they are for off road use? is this true? when i get my car smoged in a few years, would i have to take them off and install the cats?

 

they arn't technically legal, but they will pass the sniffer test. Just don't let them know they arn't stock cats, and hope they don't look at them and notice they are much smaller.

 

so do you think the kinetix would be the best since it is the only one that says it's smog legal, and it looks the most stock?

 

I don't believe the RTs will pass the sniffer test. The Crawfords or the Kinetix will, and look like a stock cat. RTs from what I've heard are raspy, but they do flow the best. Technically any aftermarket cat is illegal. The Crawfords flow second best, and then the Kinetix. Crawfords and Kinetics are less expensive than the RTs. My Crawfords on the way to me. Hope to put them in next week.

Performance Nissan sent a Z with the RT cat's to get a smog test and it passed.

The basis for Kinetix's claims relating to emissions hinges on them passing visual inspection. I have not seen or read anything that tells me they have factually passed a california sniff test. And I'm not at all saying they can't.

My high flow cats mirror the design of the La brae(sp?). I do not have any issue's with sound or annoying rasp. Only when you rev it really high in neutral do you every hear any rasp, it never does it while driving.
